Register a third-party banking user (companies only)
Company accounts register end clients as separate banking users with accounts in their name. Requires the verification_id of an APPROVED KYC/KYB verification of the third party: the type comes from the verification kind (KYC = INDIVIDUAL, KYB = COMPANY), identity data auto-fills from the verified profile (explicit fields win) and the already-validated documents are re-delivered automatically to the banking provider (documents_synced). Charges the banking profile fee (refunded if the core rejects). Person accounts get 403 company_required.
